fication, reference being had to the acco-mpanying drawings. 1

My improvements relate to the construction of brooders for the artificial raising of poultry and more particularly to the construction of the brooder compartment, the means used for supplying fresh warm air thereto, and the method of adjusting the hover therein.

In the accompanying drawings, Figure I, is a plan view of two contiguous brooders embodying my invention. Fig. II, is a central sectional elevation of the same; Fig. III, is a cross section along the 'lines- III, III, of Figs. I, and II. Figs. IV, V, and VI, are detailed views of certain parts of the warm air chimney.

be described may be separately heated, there is much saving in the use of a single source of heat. for the air supplied to an indeterminate series of such brooders. I have accordingly illustrated my invention, as thus applied to a series of brooders, two of which are shown in Figs. I, and II, of the drawings. Beneath such a series of brooders, there are formed near the floor of the brooder house, warm air compartments 1, 1. These compartments form a continuous series of any desired length and are supported above the ground on beams 2, as illustrated. The

compartments are made as nearly air-tight as 1 possible, 40

their walls being formed of double layers of boards running in different directions. The compartments are separated by intervening walls 3, through which run a series of heating pipes 4, which are thus supported within and run the entire length of the series of compartments, while yet separately heating the air in each compartment.

Each warm air compartment is provided near the bottomwith apertures 6, for the admission of fresh air. Each compartment is,

provided with a warm air chimney 7, rising centrally from the top of the compartment and passing through the floor 8, of the brooder compartment above. Upon this floor 8, is a series of brooder compartments 9, situated immediately above and correspondlng to the warm air compartments be: neath. The brooder compartments are divided by suitable partitions 10. Each brooder compartment is closed upon three sides, while upon the fourth it is provided w th a screen door 11, resting in vertical shdeways. The top of each compartment consists of a screen 14, hinged along the side 15. The chimney 7, in each brooder com partment is surmounted .and prolonged by a dome 8, the details of which are shown in Fig. V. It consists of a cylinder 17, fitting around the upper end of the warm air chimney and provided with a flange 18, at its lower edge, by which it is secured to the floor of the brooder compartment. At the proper height the cylinder 17, is much reduced in diameter by the oblique shoulder 19, and is then prolonged in the form of a warm air cylinder 20, closed at the top and which does not reach high enough to inter- .Wlnle a brooder of the character about to fere with the closing of the hinged screen 14.

The shoulder 19, of the warm air chimney is pierced by a series of apertures 21. It is also surrounded by and supports a regulating ring 22, shown in detail in Fig. VI. This is provided with apertures 23, at distances to register with the apertures 21, in the shoulder beneath, but separated by solid portions of such width that by a slight rotation of the ring, the apertures 21 may be closed to any desired extent. For the purpose of readily moving this regulating ring, the lugs 24 project from its lower rim.

The warm air cylinder 20 is used to support the hover and also to induce the proper circulation of air therethrough. This hover consists of a circular disk 30, with a depending curtain 31, as commonly used in hovers. A flanged ring 32, is inserted centrally in the disk 30, and fits over the .cylinder 20, and is adjustably supported thereon, in order to vary the height of the hover. For convenience, in regulating this height, the pe riphery of the warm air cylinder 20, is partially cut-away in the form of successive Vs, as shown in Fig. V. On one of the edges of each V, are formed a series of steps'35,

' and on the inside of the ring 32, are lugs 36,

corresponding in number to the Vs. These lugs engage and rest upon any one of said height above steps as desired, thus enabling the hover to be readily adjusted and supported at...any desired height.

in operation the heating pipes l, raise the temperature of the air in the heating compartment. Fresh air entering by the apertures 6, is thus continuously heated and passed up into the warm air chimney 7, from whence it escapes through the apertures in the shoulder of the chimney (subject to regulation by the regulating ring 22), into the hover, which, in turn, is hung at any desired the floor of the brooder compertinent.

When the hover is in its lowest position, with the lugs at the bottom of the VS, there is little *or no'escape of warm air from with in the hover through the ring 32. But as the hover is raised by advancing the lugs on the ring up the steps, the V shaped passages around the warm air cylinder are brought more and more into communication with the interior of the hover, so that adraft is induced through the ring 32, by the heated Walls of the Warm air cylinder, thus drawing an increasing quantity of fresh air beneath the curtain of the hover as it is raised to successively higher positions.

Having thus described my invention, 1 claim 1. In a brooder, a cylindrical warm air dome; a hover supported centrally and at adjustable heights upon said dome; means for regulating the escape of air from the dome to the interior of the hover; and means depending on the adjustment of the hover on the dome for regulating the escape of warm air through the top of the hover.

2. In a brooder, a hover; means for supplying Warm air thereto; a central support for the hover; means for adjusting the height of the hover upon this support; said support having escape passages of such shape that as the hover is successively advanced upon its support, an increasing escape passage is provided to permit warm air to escape from the hover,

3.. In a brooder, a cylindrical warm air dome provided with a chimney having a vertical tapered opening in its periphery, said opening being provided with a series of steps,'a hover upon said dome and adapted to rest upon the successive steps, whereby the height of said hover is varied and the air escape passages are also varied, and means for regulating the escape of warm air from the dome into the hover.

In testimony whereof, I have hereunto signed my name at Philadelphia, Pennsyl- Vania, this fourteenth day of October 1910.
